Post-laparoscopic sleeve gastrectomy changes in circulating magnesium and bone mineral density indices: A 12-month prospective study.
Article in Medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Laparoscopic sleeve gastrectomy (LSG) is one of the most popular weight-loss surgeries globally. Despite its effectiveness in weight loss, LSG may reduce serum magnesium (Mg) levels and impact bone health negatively. The current prospective study determined whether patients experienced changes in serum Mg levels and bone mineral density (BMD) for the total body, spine L1-L4, neck femur, and total hip 12 months post-LSG. A total of 51 (19 males and 32 females) out of 72 patients who underwent LSG were able to complete 12 months of follow-up. Anthropometric measurements, BMD, and serum Mg levels were assessed at baseline, as well as at 3 and 12 months after surgery. Total BMD significantly decreased in all cases by 2.6% in 3 months and by 4.3% in 12 months after surgery (P-values < .01). There was a significant increase in serum Mg levels 12 months post-LSG (+0.04 mmol/L; P < .01). In all cases, regression analysis revealed that BMD modestly but significantly explained 5% of the variations in serum Mg (β = -1.4 [standard error, SE 0.6]; P = .04) 3 months post-LSG. After a year, this perceived variance increased to 9% (β = -0.22 [0.07]; P = .006). In conclusion, both serum Mg levels and BMD are significantly altered 12 months following LSG. Whether these changes represent clinically meaningful effects or reflect transient, compensatory physiological adaptations warrants further investigation.
